QUICK SETUP  
Hint: Use good quality Alkaline Batteries; avoid rechargeable batteries.  
1. Have the Wireless Weather Station and thermo-hygro sensor 3 to 5 feet  
apart.  
2. Batteries should be out of both units for 10 minutes.  
3. Place the batteries into the thermo-hygro sensor first and next into the  
Wireless Weather Station.  
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.  
In this time the Wireless Weather Station and the thermo-hygro sensor will begin to  
communicate with each other, and the display will show both the indoor temperature  
and an outdoor temperature. If the Wireless Weather Station does not display both  
4
 
temperatures after the 15 minutes, please retry the set up as stated above. After both  
indoor and outdoor temperatures are displayed for 15 minutes you can place your  
thermo-hygro sensor outdoors, and set your time.  
The remote temperature sensor should be placed in a dry, shaded area. The remote  
temperature sensor has a range of 330 feet. Keep in mind that the 330 feet is in open  
air with no obstructions and that radio waves DO NOT curve around objects. Actual  
transmission range will vary depending on what is in the path of the signal. Each  
obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal range  
in half.  
Example: A wireless weather station receiver with a 330 feet range is mounted on an  
interior wall, so that the signal has to pass through one interior wall, one exterior wall,  
and across the 10 foot width of the room between the 2 walls. The first wall will reduce  
the range to 165 feet, and the second wall will reduce the range to 87 feet. Factoring in  
the 10 foot room, this leaves a maximum of 77 feet of remaining signal range.  
This allowance is typically enough for a frame wall with non-metallic siding; however  
certain materials can reduce range even further. Metal siding, stucco, and some types  
of glass can reduce signal range by as much as ¾ or more, compared to the ½  
reduction typical of most obstructions. It is possible to receive a signal through these  
materials, however maximum range will be much less due to their tendency to absorb or  
reflect a much larger portion of the sensor’s signal.  
NOTE: Fog and mist will not harm your thermo-hygro sensor, but direct rain must be  
avoided.  
DETAILED SET UP GUIDE  
I. BATTERY INSTALLATION (When one Thermo-hygro sensor is being used)  
1. First, insert the batteries to the Thermo-hygro sensor (see “A. Thermo-hygro  
sensor” below).  
2. Within 2 minutes of powering up the sensor, insert the batteries to the  
Temperature Station (see “B. Wireless Weather station” below). Once the  
batteries are in place, all segments of the LCD will light up briefly. Following the  
indoor temperature and the time as 12:00 will be displayed. If they are not shown  
in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds  
before reinserting them. Once the indoor data is displayed user may proceed to  
the next step.  
3.  
After the batteries are inserted, the Weather Station will start receiving data  
signal from the sensor. The outdoor temperature and humidity should then be  
displayed on the Weather Station. If this does not happen after 2 minutes, the  
batteries will need to be removed from both units and reset from step 1 and the  
signal reception icon is no longer shown.

displayed. If they are not shown in LCD after 60 seconds, remove the batteries  
and wait for at least 60 seconds before reinserting them.  
4. The outdoor temperature and humidity from the first sensor (channel 1) should  
then be displayed on the Weather station. If this does not happen and the signal  
reception icon is not shown, after 2 minutes, the batteries will need to be  
removed from both units and reset from step 1.  
5. Insert the batteries to the second sensor as soon as the outdoor temperature and  
humidity readings from the first sensor are displayed on the Weather station.  
NOTE: You must insert the batteries into the second sensor within 30  
seconds of reception of the first sensor.  
6. The outdoor temperature and humidity from the second sensor and the "channel  
2" icon should then be displayed on the Weather station. If this does not happen  
after 2 minute, the batteries will need to be removed from all the units and reset  
from step 1.  
7. Insert the batteries to the third sensor as soon as the "channel 2" icon and  
outdoor data are displayed on the Weather station. Then within 2 minutes, the  
channel 3 outdoor data from the third sensor will be displayed and the channel  
icon will shift back to "1" once the third sensor is successfully received. If this is  
not happen, user shall restart the setting up from step 1.  
NOTE: You must insert the batteries into the third sensor within 30 seconds of  
reception of the second sensor.  
IMPORTANT: Transmission problems will arise if the setting for multiple  
sensors is not followed as described above. Should transmission problems  
occur, it is necessary to remove the batteries from all units and start again the  
set-up from step 1.  
D. VIEWING AND OPERATING WITH MULTIPLE REMOTE SENSOR UNITS

III. MOUNTING  
Note: To achieve a true temperature reading, avoid mounting in direct sunlight. We  
recommend that you mount the thermo-hygro sensor on an outside North-facing wall  
(under the eve of a house is ideal). The sending range is 330 feet; obstacles such as  
walls, stucco walls, concrete, and large metal objects will reduce the range. Place the  
Wireless Weather Station and thermo-hygro sensor in their desired locations before  
8
 
permanently mounting.  
A. THERMO-HYGRO SENSOR  
1. Remove the mounting bracket from the thermo-hygro sensor.  
2. Mount using either screws or adhesive tape.  
3. Reattach the thermo-hygro sensor to the mounting bracket.  
B. WIRELESS WEATHER STATION  
1. The Wireless Weather Station comes with the table stand  
attached to the back of the Receiver. If you wish to use the table-  
stand, simply place the Wireless Weather Station in an appropriate  
location, and pull out on the attached stand.  
2. To wall mount, push the table stand flat against the Wireless  
Weather Station (if it isn’t already flat). Fix a screw (not included)  
into the desired wall, and place the Wireless Weather Station onto  
the screw using the hanging hole on the backside. Gently pull the  
Wireless Weather Station down to lock the screw into place.
